Xperia SP, the wonderful phone launched by Sony has gained world-wide appreciation. It is powered with 1.7 Ghz. dual-core Snapdragon S4 pro chipset packed with Adreno 320 GPU. Xperia SP comes with wealthy 2370 mAh non-removable battery which means that to do hard reset, we need an alternative way to switch it off.

Xperia Z also has a non-removable battery with a non-removable back casing, so in order to do a hard reset on it, one need to press and hold down “power+volume up” together for 3-5 seconds then phone vibrates, switched off and restarts. Well unfortunately the same method doesn’t work on Xperia SP.

Xperia SP Heats Up Goes dead – Won’t Turn On or Charge

Many Xperia SP users have complained that their handset heats up to extreme sometimes during charging and then remain hot for a while more than 30+ minutes. Well that’s terrible.

So What Actually Happened with us ?

At 13% battery, we put our Xperia SP on charging and when we came back after half and hour, we found our Xperia SP was very hot :/ We removed the charger and kept the phone aside. Even after 30 minutes phone didn’t cool down and the golden light in the illumination bar didn’t shut, it was lighted through out that period.

Xperia SP Won’t Turn or Charge

We were not able to get back to display screen even after pressing the power button on our Xperia SP, neither it was charging not it was turning on. For a moment we were afraid, that what happened. Phone was in on stage, it was not switched off.

Problem Solution

We thought of re-installing the firmware on our Xperia SP 12.0.A.1.257 firmware again by SUS, but before doing that we thought of doing a hard reset so that it can be switched off and restarted.

So how did we do that ? – Remember “Pressing power + Volume UP” button combination don’t work in Xperia SP.

Remove the back cover of Xperia SP and look for a small yellow dot on mid bottom with “OFF” written below it. Check the image below.

Now “Press & Hold Down the OFF Button, using a tip of pen or any other pointed object for around 10 seconds”. Phones vibrates and will be switched off automatically. Check image below.

P.S. Don’t use very sharp objects as it may damage the OFF Button.

Now phone restarts.

After restarting we found that our Xperia SP got back to normal temperature and everything was fine. 🙂 We were able to charge our Xperia SP again, device was cool.

Conclusion

Main issue is that why Xperia SP is getting this issue ? Why Phones heats up suddenly without doing nothing ? Why doesn’t it turns on ? Why doesn’t it charge ??? Many users are coming up with this issue on Sony Mobile Forums even…no proper verdict has been given by support staff on this issue.

Are these all firmware bugs or some another issue…

Please report if you have also faced same situation on your Xperia SP, report below with your problem…Comment we will get back to you soon may be with a solution…

I turned it off, then after a few minutes tried turning it on, nothing happens after pressing the power button. Then I tried plugging it to an outlet, still no response from the phone. Finally I tried pushing the OFF button behind, still no response from the phone…

I’m too facing the same problem since I’ve bought the phone. During the first time I didnot understand what happened to it and took it to sevice center there they said it was due to software problem. And after two to three months I’ve faced the same problem

My Xperia SP won’t get charged. I bought like a month ago and now, I’m not able to charge it. I connected it with the charger, both the phone and the charger are absolutely alright, since, I bought it brand new. I tried restarting my phone but it still won’t get charged. This is absolutely ridiculous.

Hi There! I’m facing the same problem here. My Xperia SP won’t charge and it’s LED keep blinking Red if I try to charge it. I once got this problem and sent it to Xperia Care (Service Centre) 3 months ago and finally got my phone back TODAY. (They took about 3 months to repair it).The SAME Problem happened again also TODAY. When I picked it up at the service center, it’s still 50% charged. Once I got home, I try to charge it, because the battery is empty and it didn’t charge. They DON’T fix anything 🙁 I’ve tried the off button method. I hold it for about 10 seconds and nothing happened. I even try to hold it for about 30 seconds and still nothing happened. Please if you can help me, that will be great. This is actually kinda frustrating. 🙁

1) My Sony XPERIA SP could not on even after I have pressed the On Button. When I charge, it has red light, but still I could not on. I tried to use the way you told but, I felt that the button is soft and still couldn’t on.

2) Besides, I am also experiencing the same thing as the above comments where my phone screen display darkens followed by some striking colours and restarts when I watched some TV channels in my phone.

Help! Sony, my phone SonyXperia C
What do I do if my off button was pressed with something sharp and looks damaged? Cause mine won’t respond at all when I push and hold it.

Hi! Guys try to install sony pc companion to your laptop or pc maybe solve youre problem, i have same problem but i try this method my sp turn on again. But after 4 hours shut off again i dont know why

Greetings, My Sony Xperia SP is nearly new. Purchased in June 2014. Yesterday in the morning the phone was fine. I left home with it fully charged. At 1 pm I took my lunch break. I found the phone was not responsive. Black screen. Could not power on. Plus it was very warm to touch. Attempted power button with volume with zero results. The phone was an unresponsive brick. Called Sony. They were a pain to deal with. Sony Support Chat was un-helpful; referred me to a phone number after telling me that they could not help. Called number; went through a ridiculous phone tree-triage. Finally found someone to talk to, but their headset/phone was terrible. Sounded like they were talking from the bottom of a well. Bottom line. I have to send the phone in for warranty repairs. I will be without the phone for more than two weeks. Lousy service; if this repair fails I will go with either a Samsung or iPhone. From the post on this forum it is obvious that Sony has a “fire phone” issue with these devices.

Hello!
Thank you very much for that article, I was already very worried and sad and thought my SP was gone for good this time.
Then from your article I learned that I had to hold the power button for 10 seconds, when I tried only 5 or so, and now it works again.
Thank you very much again for your time and effort! 🙂

Hello,my phone is not able to switch on. Im not sure why but i suspect that it is because of over charging. My screen goes off by itself and when i pressed the on button, only the display light was on. It didnt show my lockscreen or anything. I pressed the yellow button at the back of my phone and waited for 1hr but nothing happened. Should i repair my whole phone or is there any definite solution?

My Xperia SP wasworking fine but suddenly the screen blacked out and the led bar gave turquiose flashes and the screen wouldn’t turn on by any way.
I long-pressed the power button but nothing would happen.
Your solution worked then.
Well, Thank You friend

I to are have problems with this mobile it goes very hot to an extreme heat even when am using it and then when it’s off its still hot I did the pen test and it came back on after it had been off for three days it has been giving me problems like this for awhile now I don’t think that I will purchase another sony phone again I have never had problems with any other phone my main concern about these phones that if they are hot to an extreme then is there any chance that they could be a Fire Hazard

Hello,my phone is not able to display anything at all. Im not sure why but when i try to call on my mobile with another device it rings.
Even when I sent my mobile to Singapore it was sent back to me unrepaired. Why wasn’t it repaired and the price of the mobile is $499 fjd and charge for repair is $517… why is that

my Xperia Aqua is only 4 months old, i loved this phone and it was working fine until i put it down for a few minutes today and when i came back it was dead… burning hot, nothing could revive it…

i just found an online post, a guy who suggested some things to bring it back… after struggling with it for an hour, the phone is back on now but still hot and it doesn’t feel like it works the same anymore…
